GRAIN-SEPARATOR.

Specification of Letters Patent.

Patented NOV. 25,- 1913".

Application filed February 21, 1913. Serial No. 749,971.

oats from the good grain and my object is- .to provide a device of this character which will be an improvement over the other devices commonly used for this purpose.

A further object of the invention resides in providing a drum or substantially cylindrical member into which is fed the grain, the inner walls of said drum or member being lined with a fleece-like cloth and a still further object resides in providing a device adapted to contact with the inner wall of the drum to remove the wild oats and the like which adhere to this fleece-like cloth.

Still another object of the invention resides in providing means for the adjustment of the drum or cylindrical member, whereby the same may be inclined at various angles in the main frame of the device.

A still further object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

lVith these and other objects in View, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a side elevation of the device partly in section. Fig. 2 is a front elevation of the device. Fig. 3 is a vertical transverse section through the same as seen on line 33, Fig. 1. Fig. 4 is a similar view as seen on line 44:, Fig. 1, and Fig. 5 is a perspective view of the bracing bar for the chute.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a main frame consisting of end .latter in the frame. ward end of the separating drum 10 is supstandards and connecting side and end bars and mounted in the forward end of the frame at the upper portion thereof, is a grain hopper 2, the bottom of which is inclined and leads to a rearwardly and downwardly inclined chute or the like 3. The hopper 2 is provided with a slide bottom or feed adjusting plate 4 with which is connected an operating rod 5, the latter extending longitudinally of the frame 1 and to the rear end thereof, where it is provided with a handle 6 formanual actuation. Mounted in the rear end of the frame 1, is a bearing or boxing 7 in which is rotatably carried a shaft 8, the forward end of the same having isecured or otherwise carried thereon a .splder-like castlng 9. This castmg has the free ends thereof secured to the lnner end of a drum or substantially cylindrical member 10, said drum or cylindrical member flaring outwardly toward its forward end and receiving diagonally therein the longitudinal and downwardly inclined chute 3 from the hopper 2. The rear end of this member 10 is closed and the free end of this chute 3 leads to a point immediately adjacent its closed end, whereby the contents of the hopaer may be conveyed directly to the rear end of the separating member.

Supporting arms or brackets 11 which are mounted at the rear end of the frame 1 and extending outwardly therefrom, support an additional boxing or bearing 12, in which 5 is also mounted the shaft 8, the free end of the latter being provided with a crank or operating handle 13. Thus means is herein provided for supporting the rear end of the drum and for the manual rotation of the The opposite or for ported on rollers 12 which are carried in an arcuate supporting bracket 13, the latter being secured between the two end standards at the forward end of the frame 1.

The inner wall of the drum or flaring cylindrical member 10 is lined with a fleecelike cloth 14:, so that as the grain is emptied into the member 10 and caused to travel toward its forward end, the wild oats and the like will adhere to the cloth, while the clean grain will travel in its course therein to the forward end of the same. Also mounted on the frame 1, at its forward end and inclined upwardly through the drum or cylindrical member 10, is a spout or simi- .one end standard of the frame 1 and also to the spout, the same extending upwardly for a portion of the length of the latter and secured to the innermost longitudinal edge thereof. This spout is also secured to the spout or chute 3, where the same crosses the plane of the latter within the drum or cylindrical member 10 the bracing arm 15 extendino' rearwardly of the spout 15 a distance suthcient to permit the securing means 3* between the spout 3 and the spout 15 to pass therethrough and thereby afford an effective reinforcement. It will thus be seen that as the drum is rotated and the wild oats adhere to the lining therein, said oats Will be scraped from the lining and dis charged to any desired receptacle provided for the purpose of receiving such grain. The clean grain will, on the other hand, be caused to travel to the forward or flaring end of the drum or separating member 10, where it is emptied into a separate receptacle or the like for receiving the same. Thus by emptying the grain in the rear end of the separating member 10, the wild cats will be effectively removed therefrom, with little or no trouble.

I have provided means for the disposition of the one end of the frame 1 upwardly or downwardly with respect to the opposite end thereof and to this end, a frame 16 is provided, the same being adapted for adjustment between the end standards at the rear end of the frame 1 below the lower cross bar thereof. Adjusting bolts 17 which are carried by the upper bar of this frame 16, extend through threaded sockets in this lower transverse bar at the end of the frame 1 and by adjusting said bolts 17 it will be seen that the frame may be raised or lowered to correspondingly raise or lower the referred to end of the frame 1. By this action of raisin or lowering the one end of the frame, t e separating drum carried therein may be disposed at various angles with respect to the ground.

From the foregoing description of the construction of my improved device, the operation thereof will be readily understood and it will be seen that I have provided a simple, inexpensive and efiicient means for carrying out the objects of the invention.

While I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention, what I claim is 1. In combination with a frame provided with a hopper, of a drum rotatably mounted in said frame, a spout extending diagonally downward through the drum and contacting with the inner walls thereof, an angular bracket secured to the frame and to the spout and extending rearwardly thereof a predetermined distance whereby such spout is maintained in operative position, a second spout leading from the hopper downwardly through the drum to the rear of the latter, and connecting means between both of the spouts whereby the latter spout is maintained in operative position.

2. In combination with a frame having a supply hopper, of a drum rotatably mounted in said frame, a spout extended inwardly and upwardly of the frame and adapted to contact with the inner walls thereof, means carried by the frame for maintaining the spout in such position, a chute depending inwardly and downwardly within the hopper, and means coacting with the spout and chute for maintaining the chute against displacement from within the drum.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
